In this paper we study empirically the validity of measures of referential success for referring expressions involving gradual properties. More specifically, we study the ability of several measures of referential success to predict the success of a user in choosing the right object, given a referring expression. Experimental results indicate that certain fuzzy measures of success are able to predict human accuracy in reference resolution. Such measures are therefore suitable for the estimation of the success or otherwise of a referring expression produced by a generation algorithm, especially in case the properties in a domain cannot be assumed to have crisp denotations. © 2018 Association for Computational Linguistics

Astrophysical neutrinos may be produced during the coalescence of compact objects, in particular those involving neutron stars. Such mergers have been identified through gravitational wave detections by the LIGO and Virgo collaborations and reported in published catalogs. The ANTARES and KM3NeT deep-sea neutrino telescopes are sensitive to neutrino interactions in a wide range of energies, from MeV to PeV. The under-construction KM3NeT telescope covers this energy range with two detectors: ORCA for neutrinos below the TeV and ARCA for TeV–PeV, extending the capabilities of the now-decommissioned ANTARES telescope. This contribution presents the search for neutrinos in time and space correlation with the gravitational wave signals reported during the Third Observing Run of LIGO/Virgo. The ANTARES analysis uses track-like and shower-like events originating from high-energy neutrino interactions. It focuses on a ±500-second time window centered on the time of the merger given by the gravitational wave signal. Two KM3NeT studies are carried out using the data from the partial KM3NeT/ORCA detector: a search for upgoing tracks induced by GeV-TeV neutrinos in the same window as above;and a search for a MeV neutrino signal in a shorter 2-second time window. The results are provided in terms of upper limits on the incoming neutrino flux in the various energy ranges and the total isotropic energies emitted in neutrinos. High-energy observations are also stacked to probe the typical neutrino emission from different populations of mergers. The complementarity of ANTARES and KM3NeT results is also explored. © Copyright owned by the author(s) under the terms of the Creative Commons.

This paper shows an analysis of the time offset error introduced into a highly accurate packet-based time synchronization link by the most frequently deployed long distance network components. Translating the sub-nanosecond accuracy of a White Rabbit timing link into long distance fiber communication networks is a very demanding task. With the increased distance the need for devices that keep the integrity of the signal and maintain its power across hundreds of kilometers is beyond question. Some of these devices might suffer from large disparities in their environmental conditions due to being placed in distant locations from each other, potentially varying their behavior. The results demonstrate that moderate temperature disparities can lead to timing offset errors of several nanoseconds. This outcome can be seen as the foundation laid for a series of compensation techniques to be developed in future work.

One of the main challenges of spatial audio rendering in headphones is the crucial work behind the personalization of the so-called head-related transfer functions (HRTFs). HRTFs capture the listener's acoustic effects allowing a personal perception of immersion in virtual reality context. This paper aims to investigate the possible benefits of personalized HRTFs that were individually selected based on anthropometric data (pinnae shapes). Personalized audio rendering was compared to a generic HRTF and a stereo sound condition. Two studies were performed;the first study consisted of a screening test aiming to evaluate the participants' localization performance with HRTFs for a non-visible spatialized audio source. The second experiment allowed the participants to freely explore a VR scene with five audiovisual sources for two minutes each, with both HRTF and stereo conditions. A questionnaire with items for spatial audio quality, presence and attention was used for the evaluation. Results indicate that audio rendering methods made no difference on responses to the questionnaire in the two minutes of a free exploration. © Proceedings of the 15th Sound and Music Computing Conference: Sonic Crossings, SMC 2018.

Schizophrenia (SZ) is a mental disorder whereby due to the secretion of specific chemicals in the brain, the function of some brain regions is out of balance, leading to the lack of coordination between thoughts, actions, and emotions. This study provides various intelligent deep learning (DL)-based methods for automated SZ diagnosis via electroencephalography (EEG) signals. The obtained results are compared with those of conventional intelligent methods. To implement the proposed methods, the dataset of the Institute of Psychiatry and Neurology in Warsaw, Poland, has been used. First, EEG signals were divided into 25 s time frames and then were normalized by z-score or norm L2. In the classification step, two different approaches were considered for SZ diagnosis via EEG signals. In this step, the classification of EEG signals was first carried out by conventional machine learning methods, e.g., support vector machine, k-nearest neighbors, decision tree, naïve Bayes, random forest, extremely randomized trees, and bagging. Various proposed DL models, namely, long short-term memories (LSTMs), one-dimensional convolutional networks (1D-CNNs), and 1DCNN-LSTMs, were used in the following. In this step, the DL models were implemented and compared with different activation functions. Among the proposed DL models, the CNN-LSTM architecture has had the best performance. In this architecture, the ReLU activation function with the z-score and L2-combined normalization was used. The proposed CNN-LSTM model has achieved an accuracy percentage of 99.25. © 2021, CC BY-NC-ND.

Several methods for creating building-related Linked Data graphs exist. This paper focuses on the conversion of IFC Building Information Models (BIM) to RDF Abox graphs using the emerging W3C Linked Building Data (LBD) modular ontologies: BOT (building topology), PRODUCT (classification of building elements) and PROPS (building-related properties). The existing IFC-to-RDF converter tool, converts IFC into ifcOWL-based Abox graphs which are rather complex and difficult to implement in software applications. The IFC-to-LBD converter presented, is necessary to transform IFC building models into RDF Abox graphs structured according the new LBD ontologies. An output graph contains the relevant information of the IFC building model related to building topology, building elements classification and building-related properties. Additionally, the graph structure becomes more concise (minimum 83 % less triples) and significantly easier to query compared to the output of the ifcOWL-based IFC-to-RDF converter. © 2018 CEUR-WS.

he White Rabbit (WR) technology has been introduced as an enhancement and next generation of the Precision Time Protocol (PTP, IEEE 1588), providing a boost in synchronization accuracy from the usual sub-microsecond range commonly found in PTPv2-based applications, down to the much more precise sub-nanosecond range. A number of White Rabbit-capable network nodes have been developed with the goal of allowing simultaneous deterministic time transfer and regular Ethernet data traffic to coexist on the same link without significant performance degradation over fiber links spanning tens of kilometers. The first SoC-based platform amongst these nodes is the WR-ZEN board, which implements a real-time White Rabbit stack in the Programmable Logic (PL) of the Zynq-7000 SoC;and features a hardened, ARM dual-core Processing System (PS) for running an embedded Linux environment. This paper presents the work carried out to upgrade the WR-ZEN board implementation, whose peak data throughput is limited just below 70 Mbps, so that a 1 Gbps data rate can be attained without impacting the performance of the White Rabbit synchronization. This goal is fulfilled by designing additional custom logic based on the Xilinx AXI DMA core, as well as an updated Linux network driver. This enhancement allows the widespread deployment of the WR-ZEN for major scientific infrastructure projects that require high-speed data transmission and deterministic timing transfer, as is the case of telescope arrays. Lastly, experimental results are presented comparing the synchronization performance of a baseline PTP-based setup to that achieved on the enhanced WR-ZEN board in the presence of high throughput data traffic. Conclusions are drawn and potential scientific and industrial applications that tap this increased bandwidth with deterministic timing transfer are discussed. © 2017 IEEE.

Shape analysis, and particulary the contour study, is a fundamental task for object recognition in images. In this paper, a fuzzy approach for representing the linearity property of a contour segment is proposed. Linearity is a key property related to which degree a contour segment is a curve or a straight line;in addition, it is the basis for modelling other properties like curvature, salience or concavity/convexity. In this framework, firstly, the idea of linearity vs non-linearity, and the meaning of its fulfilment, will he analyzed. Secondly, the definition of a membership function according to that meaning will be proposed on the basis of the coefficient of determination. Finally, we will show the goodness of our proposal by analyzing linearity in a set of shapes with different characteristics.

In this paper, we propose a cybersecurity exercise system in a virtual computer environment. The human resource development for security fields is an urgent issue because of the threat of cyber-attacks, recently, is increasing, many incidents occurring, but there is a not enough security personnel to respond. Some universities and companies are conducting education using a commercial training system on the market. However, built and operates the training system is expensive, therefore difficult to use in higher education institutions and SMEs. However, to build and operates, the training system needs high cost, thus difficult to use in higher education institutions and SMEs. For this reason, we developed the CyExec: a cybersecurity exercise system consisting of a virtual computer environment using VirtualBox and Docker. We also implemented the WebGoat that is an OSS vulnerability diagnosis and learning program on the CyExec and developed an attack and defense exercise program.

Joint direct estimation of 3D geometry and 3D motion using spatio temporal gradients

Conventional image motion based structure from motion methods first compute optical flow, then solve for the 3D motion parameters based on the epipolar constraint, and finally recover the 3D geometry of the scene. However, errors in optical flow due to regularization can lead to large errors in 3D motion and structure. This paper investigates whether performance and consistency can be improved by avoiding optical flow estimation in the early stages of the structure from motion pipeline, and it proposes a new direct method based on image gradients (normal flow) only. The main idea lies in a reformulation of the positive-dept. constraint, which allows the use of well-known minimization techniques to solve for 3D motion. The 3D motion estimate is then refined and structure estimated adding a regularization based on dept.. Experimental comparisons on standard synthetic datasets and the real-world driving benchmark dataset KITTI using three different optic flow algorithms show that the method achieves better accuracy in all but one case. Furthermore, it outperforms existing normal flow based 3D motion estimation techniques. Finally, the recovered 3D geometry is shown to be also very accurate. Copyright © 2018, The Authors.
